Abstract
A probe head having a probe head base and a stylus is provided for contacting a surface point on a workpiece. The stylus is moveable relative to the probe head base and has a defined rest position relative to the probe head base. For the contacting, the probe head is moved relative to the workpiece until the stylus touches the surface point with a defined contacting force. A correction data record representing a hysteresis behavior of the stylus with respect to the rest position is provided, and the contacting force is determined using the correction data record.
